TO ALL WHOM IT MAY CONCERN:

Be it known that I, JON W. SCHRIBRR, of New York, inthe lcounty of NewYork, and State of New York, have invented a new andinseful Improvementin Lampfliurners; and I do-hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin tho art te` make and use the same, reference being had to theaccompanying drawings forming part of this specificatiom in which-Figure 1 represents a vertical` transverse section of my improvedlampbnrner,V

Figure 2 is a vertical longitudinal section of the same.

Similar letters .of reference indicate like parts. 4

This invention relates to a new burner for eoalfoil and other lamps,itsobjet being to cause'thc complete combustion oi' all the oil elevatedby the wick.

The invention consists,- first, in supporting theA lamp-chimney on lugs'or 'springs that project from the solid base of the burner, so that anopen space is left below the lower edge of thc chimney for the air topass to the outside of the ame.

The invention consists, second, in the use ot' an outer wicktube, whichreaches-abovc-the upper 'endet the .main wick-tube, and which .restsupon springs, that hold it as high up as possible, so that a horizontalcircular plate projecting from it is held against a contracted portionofthe chimney; v

The invention also consists in hinging the cap of the burner to theaforesaid circular plate, or to the plate upon which it rests, so thatit can befoldcd back to facilitate the lighting ofthe lamp.-

' The invention finally consists in so shaping the cap that it will',although itvhas a circular base,ine|t be conical, but with iiat sides,so that the air is more equally conducted to the flame.

A, in the drawing, represents the body or dead-air chamber ot' alamp-burner.

B is thc main wick-tube arranged therein. i, i

C is the upper plate of the body, and the base-pluto of the upperappendage o'f the same. i

The plate Cprojects from the sides of the body, as shown, and is notperforated, except where the wicktube passes through it.y

D represents a secondary wick-tube. The sume is fitted around the upperportion of the main tube B, and projects above the same, as is clearly.shown'in thc drawing.

From the tube D projectsapcrforated plate, E, between which, and thebaseiplate, springs a t are arranged, that serve to elevate the tube D,and its appendages, they forming thc supportof the same. i

F F are spring-holders, attached to the plate C, and projecting upon andfrom the saine. They are bent inward, as at in iig. 2, or arc otherwiseprovided each with `a shoulder, IJ, tenablc them to support the chimneyabove the plate C, thereby an open space is produced between thc loweredge of the chimney andthc plate C,

for the air `to pass in. 4

The chimneys to bc used in connection with this burner are to 4have acontracted portion opposite the plate E, the said plate E being, bymeansof thc springs a, held against the narrow partof the chimney, as :isclearly shown in fig. 2, and, as not all chimneys are-made exactlyalike, the springs a will cause the plate E to adjust itself` tochimneys in which the contractedportion is higher or lower. i

G is the cap of thc burner. rlhe same is not of trnly conical shape, buthas its upper partnnarrow, parallell with the slot. Heretoiorc the capswere always made conical, and were therefore wider opposite thc middleof the slot than they were opposite the ends of the same, and a' largersupply of air was consequently brought to the middle of the iiaic thanto the ends of thesaine By making the upper part of the cap narrow, ,anequal supply of air willbe brought to all parts 'of the flame. i

The cap G is hinged to thc plate E. as shown, to allow-'its being easilyswung open, for the purpose of facilitating the 'lighting of thc lampFrom the plate C projects a rod, H, which serves to support and `hold a'reiiector on the outside of thr` chimney, as indicated in figs. 1 and 2.

Having thus described my ipven'tlonhl claim as new, end deere to secureby Letters Patentl.l The secondary tube D, arranged around themeinwek-tu'be of a burner, and projectingv above the some, when saidsecondary tube'is, by means ofrsprlngs a a, that t under a. plate, E,projecting fron: the tube, held up, and lzrdjuxted up -:md downv,`as'sel; forth. v .f 1 y l .l 'A

2. Closing the chimney of la. lamp-burner', by means of a', perforatedplate, E, whioh ie held up ngans: a* contracted portion ofthe chimney bymeans of springal a, -us described, so that all the. oir willhavelo'pnseto the llame throxgh 'che said plate E.

3. A lamp-burner, consisting of `the`borvly`,`tlube gland base-plateC`,Iin combnatlon with tb'e'secondory 4 tubeD, perforated plate E,springs @cop G, and `@ring-lm lders F F, or their equivalents, all madeand operat ing substantially as hereinhow'and described.- A
